6. Functions and Precautions
6-1. Input Voltage Range
Input voltage range is single phase 85 ~ 265VAC (47 ~ 63Hz) or 120 ~ 350VDC. Input voltage, which is out of
specification, may cause unit damage. Rated input voltage for safety standard application is 100VAC-240VAC (50/60Hz).
6-2. Output Voltage Range
Output voltage is set to the rated value at shipment. V.ADJ trimmer on the front panel side can be used to adjust the
output voltage within the range specified (refer to specifications for adjustable range).
To turn the trimmer clockwise, the output voltage will be increased. Take note when the output voltage is increased
excessively, over voltage protection (OVP) function may trigger and output voltage will be shut down.
6-3. Over Voltage Protection (OVP)
The OVP function (Inverter shutdown method, manual reset type) is provided. OVP function operates within specified
range (refer to specification) of the rated output voltage value and the output will be shut down when OVP function
triggers (refer to specifications for OVP range of each models). To reset OVP, remove the input of power supply for a
few minutes, and then re-input. Or, use CNT to reset (remote ON/OFF: OFF to ON). OVP value is fixed and not to be
adjusted externally. Never apply more than rated output voltage to output terminal, which may leads to damage. In the
case of inductive load, use decoupling diode at output line.
6-4. Over Current Protection (OCP)
OCP function is provided. OCP characteristic is constant current limiting, automatic recovery. OCP default value is
set at 85 ~ 95% of output current at shipment.
OCP function operates when the output current exceeds OCP setting value (default: 85 ~ 95% of maximum DC
output current specification).
The output will be automatically recovered when the overload condition is removed. OCP.ADJ trimmer on top panel
of HWS600L-*/BAT or right side panel of HWS1000L-*/BAT can be used to adjust the OCP operation current within
the range specified (refer to specifications for adjustable range).
By turning the trimmer clockwise, the OCP operating current will be increased.
Never operate the unit under overload or shorted conditions continuously beyond the 100% output current rating as
this may lead to damage.
Constant Current Setting accuracy is +/- 10%. In case of Output Voltage less than 50% during OCP operating, setting
accuracy might be over +10%. Avoid to operate at Constant Current condition that output voltage is less than 50% of
rated output voltage .
OCP ADJ trimmer is located in primary circuit. OCP ADJ trimmer should be adjusted by skilled person once this
product to be installed into the equipment. See 6-17.

Measurement circuit as below measures the standard specification for maximum ripple value. When load lines are longer,
ripple becomes larger. In this case, electrolytic capacitor, film capacitor, etc. might be necessary to use across the load
terminal. The output ripple cannot be measured accurately if the probe ground lead of oscilloscope is too long.
6-10. Battery Charger Applications
By using the OCP function, HWS600L-*/BAT and HWS1000L-*/BAT can be used in battery charger applications.
When connecting with these devices, put Oring-diode on the output line as shown in fig. below.
In case of any failure on the power supply side, please take safety measures to prevent large reverse current flow from
the battery to the power supply unit.
Heat will be generated by power losses due to diode forward voltage Vf and output current Io
(Pd = Vf × Io). Therefore, the diodes must be cooled.
In addition, please use power supply within the rated output voltage and output power specification.
Constant Current Setting accuracy is +/- 10%.
In case of Output Voltage less than 50% during OCP operating, Setting accuracy might be over +10%.
Avoid to operate at Constant Current condition that output voltage is less than 50% voltage .
